No-Bake Mini Key Lime Pie Cups

Creamy Citrus Dessert Perfect for Summer Gatherings

My daughter came home from a beach trip last summer and would not stop talking about these little Key Lime Pie Cups she had at a tiny café overlooking the water. She begged me to recreate them, so on a random Tuesday night I grabbed a few pantry staples and gave it a try.

The result? Pure sunshine in dessert form.

These no-bake mini key lime pies are creamy, tangy, and perfectly sweet with a buttery graham cracker crust that stays deliciously crisp. Topped with fluffy whipped cream and fresh lime zest, they're elegant enough for baby showers, brunches, summer parties, and holiday dessert tables while being incredibly easy to make.

The best part? No oven, no complicated steps, and no stress. Just mix, chill, and enjoy one of the easiest make-ahead desserts you'll ever serve.
